Compost quality attributes, measurements and variability

Creator:: Sullivan, Dan M. and Miller, Robert O.
Abstract:: This chapter addresses compost quality specifications, chemical and physical properties of compost, evaluation of compost maturity and stability, and variability in compost analytical data.
Resource Type:: Part of Book
Full Text:: ash concentrations. The portion of the sample lost in high temperature combustion (550 oC

River Microbiome Composition Reflects Macroscale Climatic and Geomorphic Differences in Headwater Streams

Creator:: URycki, Dawn R., Good, Stephen P., Crump, Byron C., Chadwick, Jessica, and Jones, Gerrad D.
Abstract:: Maintaining the quality and quantity of water resources in light of complex changes in climate, human land use, and ecosystem composition requires detailed understanding of ecohydrologic function within catchments, yet monitoring relevant upstream characteristics can be challenging. In this study, we investigate how variability in riverine microbial communities can be...

Building a multi-scaled geospatial temporal ecology database from disparate data sources: fostering open science and data reuse

Creator:: Soranno, Patricia A., Bissell, Edward G., Cheruvelil, Kendra S., Christel, Samuel T., Collins, Sarah M., Fergus, C. Emi, Filstrup, Christopher T., Lapierre, Jean-Francois, Lottig, Noah R., Oliver, Samantha K., Scott, Caren E., Smith, Nicole J., Stopyak, Scott, Yuan, Shuai, Bremigan, Mary Tate, Downing, John A., Gries, Corinna, Henry, Emily N., Skaff, Nick K., Stanley, Emily H., Stow, Craig A., Tan, Pang-Ning, Wagner, Tyler, and Webster, Katherine E.
Abstract:: Although there are considerable site-based data for individual or groups of ecosystems, these datasets are widely scattered, have different data formats and conventions, and often have limited accessibility. At the broader scale, national datasets exist for a large number of geospatial features of land, water, and air that are needed...

Exploring biophysical linkages between coastal forestry management practices and aquatic bivalve contaminant exposure

Creator:: Scully-Engelmeyer, Kaegan, Granek, Elise F., Nielsen-Pincus, Max, Lanier, Andy, Rumrill, Steven S., Moran, Patrick, Nilsen, Elena, Hladik, Michelle L., and Pillsbury, Lori
Abstract:: Terrestrial land use activities present cross-ecosystem threats to riverine and marine species and processes. Specifically, pesticide runoff can disrupt hormonal, reproductive, and developmental processes in aquatic organisms, yet non-point source pollution is difficult to trace and quantify. In Oregon, U.S.A., state and federal forestry pesticide regulations, designed to meet regulatory...

Spatial Patterns of Chemical Weathering at the Basal Tertiary Nonconformity in California from Multispectral and Hyperspectral Optical Remote Sensing

Creator:: Sousa, Francis J. and Sousa, Daniel J.
Abstract:: Visible through shortwave (VSWIR) spectral reflectance of the geologic units across the basal Tertiary nonconformity (BTN) is characterized at three spatially disparate locations in California. At two of these sites, location-specific spectral endmembers are obtained from AVIRIS imaging spectroscopy and linear spectral mixture models are used to visualize spatial patterns...

Spatiotemporal distribution of the anti-diabetic drug, metformin, in the lower Columbia River and its effect on phytoplankton growth

Creator:: Cummings, Brittany M.
Abstract:: Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...

The role of molecular architecture in the hydration properties of brewers’ spent grain

Creator:: Yang, Jasmin S.
Abstract:: An emerging strategy to reducing food waste is converting food processing byproducts to nutritious and inexpensive food ingredients. A relevant food processing waste stream is brewers’ spent grain (BSG), the primary byproduct of beer production. BSG is a promising candidate as a food ingredient because of its high protein and...

Grassland Arthropods Are Controlled by Direct and Indirect Interactions with Cattle but Are Largely Unaffected by Plant Provenance

Creator:: Farrell, Kelly Anne, Harpole, W. Stanley, Stein, Claudia, Suding, Katharine N., and Borer, Elizabeth T.
Abstract:: Cattle grazing and invasion by non-native plant species are globally-ubiquitous changes occurring to plant communities that are likely to reverberate through whole food webs. We used a manipulative field experiment to quantify how arthropod community structure differed in native and non-native California grassland communities in the presence and absence of...

The Evolution of Scleractinian Microbial Symbionts

Creator:: McMinds, Ryan C.
Abstract:: The modern world has presented many threats to the health and stability of ecosystems worldwide. One of the most biodiverse ecosystems, coral reefs, faces particularly strong pressures, and is already declining rapidly in complexity and area. Although the stressors that affect reefs are diverse, ranging from nutrient pollution to overfishing,...

Online language teaching research : pedagogical, academic and institutional issues

Creator:: Sanz-Sánchez, Israel, Rivera-Mills, Susana V., and Morin, Regina
Abstract:: With the growth of Internet technologies, online-based foreign language curricula are being introduced at large numbers of institutions internationally. This peer-reviewed volume, geared towards a broad audience, presents innovative research on online language teaching, with chapters by highly engaged scholars and practitioners from the U.S. and Europe, with a strong...
